The latter is driven from the belt pulsteep carried along with it to the air. If ley 66. t the supply of steepin liquor should be too From the shaft 42 which is rotated by the belt Ipulley 66 the steeping roller and the belt 31 are also driven. On the other end of the main shaft 42 is mounted the chain wheel 43 which coactsthrough the chain 44 with the` chain wheel 45. The latter is mounted on tige t e pin 65 fixed in the bearing 64 and acts) through the chain 47 on the chain wheel 48 driving the shaft 49. On the other end of the shaft 49 is the toothed wheel 50 which meshes on the one hand with the wheel 51 keyed on the shaft of the lower steeping roller and on the other hand with the toothed wheel 52 which drives the rubber roller 28 and cdacts with the wheel 53 xed on the shaft of the` roller 25. In this way not only the spongy rubber belt 16 is driven but the belt 31 as well.

On the shaft 49 there is also mounted the chain wheel 54 which through the chain 55 (Figure 2) drives the chain wheel 56 and theI rubber roller 57 which is mounted vbelow the brush roller.` The roller 5 7 rests in the bearings 58/f1xed on jthe standards 5and 6 and serves the purpose of guiding th'e endless conveyor band 59 which also yruns over the roller 60 The latter roller is also journalled in two bearings 61 which are fixed on the main standards and is capable pf being adjusted by means of the hand wheels 62 and the screw spindles 63.

To one of fixed for measuring the quantity of steep worked into the pelts. This measuring device conslsts of a liquid pressure ,gauge 67 in combination with a flexible rubber tube 68 and a glass tube 69 which extends intothe s'teeping li uor in the storage tank 17 so that. the level o the liquor can be read any time on the scale of the pressure gauge. The pres-,vl

sure gauge scale 1s so graduated that one scale division corresponds to one litre of the quantity of liquor used, so that the latter can be read olf at any time on the scale for a definite number of pelts.-

It is of the greatest4 importance to check accurately the quantity of liquor for the pelts to be steeped, as a definite prescribed quantity of liqluor is required according to the kind of pe t in order to ensure a satisfactory further treatment of the hair materials in the manufacture of hats. The prcvision of the measuring device makes it possible so to regulate the supply of liquor that the correct quantity lof steeping liquor shall be app' pliedto the pelts to be steeped.

The machine operates in the following manner:

rapidly than the belt ,y compresses the spongy ru the housings 7 or 8 a device isi'r uid tank below said rollers` a wing belt extending into said tank and rpassing over one of said rollers, \means located at the discharge side of said ing rollers for great, the squeegee ro lor 20 is pressed with` somewhat greater force against the spongy rubber belt 16 whereby a portion of the liquor is pressed out of the latter. After passing the steepirig rollerl the pelt travels between the-rollers 25 and 26 and ispushed by them against brush roller 38. The brush roller deiiects the pelt upwards and plresses it against the belt 31 which runs at t e same velocity as the steeping rollers 9 and 10. The pelt thus lies between the belt 31 and thebrush roller 38, so that the latter which runs more 31 brushes the steeping liquor well into the hairs of the pelt. After the operation is com lete the pelt falls on to the endless conveyor and 59 and is conveyed away by it. Through the belt 31 being used any splashing of the steeping liquor while it 1s being rubbed on is prevented. The persons attending the machine are therefore protected from the injurious eectsof the steep.

After adenite number of pelts has passed through the machine, the volume of the quantity of steep used in treating them is read olf o'n the liquid pressure gauge. In this way the quantity can be constantly checked which is of the greatest importan 1n the further treatment of the hair in the manufacure of hats. Should the operative judge that the consumption of steep is too great, he

ber belt more strongly by means of the two squeegee rollers 19 and 20 and if the consumption is too small he separates the rollers slightly more. 'I he operative is thus able to regulate the action of the machine as desired.

y2. A machine for steeping pelts including a ypair of cooperating pelt feeding rollers, a liquid reservoir arranged below said rollers, a sponge rubber belt extending into said reser` oir and passing over the lower one of said pe tffeeding rollers, and brushing means arranged at the discharge side. of said pelt feedhairs of the pelt. l

3; A. machine for steeping pelts including a pair of pelt feeding rollers, a liquid reservoir arranged below said rollers, an endless liquid supplying belt extending into the resl' ervoir and passing over brushing the liquid into the w the lower one of said 13 rollers, a pelt conveyor, brushing meansv arranged between the pelt feeding rollers and said conveyor, said brushing means being adapted to receive the pelt from the pelt feeding rollers and'brushing theliquid intov the hair of the pelt while moving it toward said pelt conveyor.

4. A machine for steeping pelts comprising a pair of pelt feeding rollers,.a steeping liquid reservoir arranged beneath said rollers, an endless liquid supplying belt extending into the reservoir'and passing over the lower one of said pelt feeding rollers,'and brushing means arranged at the discharge side of said pelt feeding rollers, said brushing means comprising a'rotary brush, pelt gulding rollers arranged between the rotary brush and the pelt feeding rollers, and an endless belt passing over the upper one of said pelt guiding rollers and having the lower reach thereof extending over and about the rotary brush. f

- 5. In a pelt steeping machine, pelt feeding rolle-rs, means for supplying steeping liquid to a pelt passing between said feeding rollers, and means for brushing the liquid supplied to the pelt into the hairs thereof comprising a pair of pelt guiding rollers, a rotary brush arranged at the discharge side of said rollers and an endless belt passingover the upper one of said pelt guidingl rollers and having the lower reach thereof extending over and about said rotary brush whereby the liquid carried by the liairs of 'the pelt may be brushed into the same.

6. A machine for carrotting pelts comprising, in combination, a tank for the carrotting liquor, a roller arranged over the tank,

.an endless belt of porous elastic material running over said roller and dipping into the( carrotting liquor in the tank in order to convey and press the liquor into the pelt, a counter-pressure roller arranged over the belt-roller and coacting therewith, a brush at thedischarge side of said rollers for distributing the liquor into the pelt, and a second belt of elastic material arranged over the brush and partially embracing the same.

7. In a machine for carrotting pelts, rollers adapted to receive the pelt with the hair side downward, means in the form of an endless porous belt for supplying carrotting liquor to the hair side of the pelt in regulated quantity, and means for brushing the liquidsupl plied tothe hairs of the pelt comprising a or,

rotary brush and a flexible covering there the rotary brush and the cover rotating at different speeds whereby the brush works the liquid into the hair as the pelt is pressed against the flexible cover and the pelt is simultaneously moved to be discharged from the machine.
